Oh cool! That rings a bell! :)<p>I wrote and am operating a similar service at <a href="http://remaildr.com" rel="nofollow">http://remaildr.com</a><p>The implementation is open source at <a href="https://github.com/Pluies/remaildr/" rel="nofollow">https://github.com/Pluies/remaildr/</a><p>The main issue I've had with this side project is the availability that wasn't so great (as monitoring was conspicuously absent from the start and I never got around to actually setting it up, but I've got plans for it!) and it was eventually caught by spam due to Spamassassin misconfiguration on my part.<p>So I hope you have a good process for handling spam, and fingers crossed your code crashes less often than mine :)
